The really big action—the Penn and Drake Relays and the London Marathon—is yet to come, but today’s limited action is still first-rate. The Pole Vault on Court Avenue, a street vault held in downtown Des Moines in conjunction with the Drake Relays, will begin at 5:15pm local time (6:15pm ET).

Lavillenie is the world record holder and the undisputed #1 vaulter in the world. Kendricks won the USATF indoor championship last month and the outdoor title last June, where Hollis was runner-up. Walker is on the downside of his career but is the most decorated of all active US vaulters, with five medals at World indoor and outdoor championships.

Suhr and Silva were the world’s top two vaulters last year, but Stefanidi had the best indoor season of the above. Suhr struggled with injury through the indoor season (and Silva just didn’t compete), but no one is better when they’re at full power. Saxer was runner-up at the US indoor championships (behind collegian Demi Payne). A leser-known name, Lotout was fifth at the European indoor championships.

Tomorrow—the Penn and Drake Relays begin in earnest, and we’ll let you know what to watch in nearly every event!
